Hello there !
My friend found today a way to prevent crashing on loading on most maps (i couldn't even load reserve, and had crashes on custom half the time …) and i'm here to share it with you guys :
1st step (optional but advised) : Open a new console in admin mode : type "sfc /scannow". It will check your Operating System for corrupted system files and repair them.
2nd step : Open file explorer, right click on "This pc" -> properties -> remember your RAM (MBytes) -> advanced system settings -> performance settings -> tab "advanced" -> virtual memory -> change -> set a personalized quantity of memory : initial and max -> set them to your RAM in MBytes (Edit : someone recommanded to make it 1.5 your RAM).
3rd step : reboot and you're done !
That's all, it works really well on my EfT, hope i've helped some of my fellow PMCs, see you on the field !
